Workaround for a VNC session inside of a VNC session?

[tmwhirl]

I have been trying to find a way to work around needing to use a VNC inside of a VNC for various reasons, so I am curious if there is a way to path from one PC through another into a 3rd PC.

As a example of what I am trying to accomplish:

Personal work station, A, has an address of 192.168.1.100, there is a remote station, B, that acts as a local host and only point of entry for several other stations and addressed as 192.170.1.100, and the station, C, I am trying to reach is addressed as 10.10.10.100. I can easily use A to access B, open another VNC session within B to access C, but ultimately this causes issues because it effectively ties up B while I am trying to do something on C, so I would like to go from A to C directly. Is it possible?

Thanks in advance.
